SMS Gateway is an all-round solution for different text messaging services suitable for companies with technical know-how. It is easy to implement different SMS services using our SMS Gateway service. It can be effortlessly used for SMS payment services as well.

SMS Gateway connects the message centres of various mobile telephone operators and provides a single easy-to-use interface for sending and receiving text messages. Message traffic is passed between the customer and Labyrintti Media using Internet connections. The actual service application is usually produced by the customer and runs on the customer's own servers as a PHP script, a Java Servlet or another type of server application. If required, Labyrintti Media can also create the service application and arrange service hosting as a complete turnkey package.

SMS Gateway is divided into two separate services:

  • Unidirectional SMS Gateway enables the sending of text messages from the customer's system to mobile telephones.
  • Bidirectional SMS Gateway enables reception of text messages as well as the sending of text message replies back to mobile telephones. The users may also be charged for using the service as a part of their telephone bill.
